"A lot of tropical ecology and conservation science is actually published by scientists who are outside of, or not from, the tropics," says Perez, an alumnus of the University of Vermont. "One motivation for this study was to see if scientists outside of the tropics are starting to collaborate with scientists within the tropics."

Perez's study does not undermine the hard work that scientists do in the tropics, but rather seeks to determine if that work is happening in a bubble. If so, he notes, important information could go unshared.
